Application March 28,

5 Claims.

This invention relates to what is known in the art of well drilling and pumping as lazy boards, or devices for supporting within a derrick the sections of pipe, tubing or the like as they are disconnected and stacked in an upright position in the derrick so as to be arranged for convenient reconnection into a string to be lowered into the well.

An object of the present invention is to provide a lazy board which may be utilized in such number as to support in an upright position within a derrick as many sections of pipe or tubing as may be necessary in drilling or pumping the well, and which embodies novel means for holding the sections with great security so as to prevent them from accidentally falling or twisting, although permitting ready and intentional removal of said sections in their proper order for reconnection and use.

With the above and other objects in view, my invention consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings:

Figure 1 is a horizontal section of a derrick equipped with lazy boards in accordance with my invention.

Figure 2 is an enlarged fragmentary vertical section on the plane of line 2-2 of Figure 1, certain of the brackets or clips being shown in open position.

Figure 3 is an enlarged horizontal section on line 3-3 of Figure 2; and

Figure 4' is a vertical section on line 4-4 of Figure 3.

In carrying out my invention, I provide a transverse beam 5 within the derrick, parallel with and adjacent one side of the latter, and swung from opposite cross beams 6 of the derrick below the beam 5 and between the latter and the adjacent side of the derrick is a platform I forming a walk for a workman.

Supported at its ends by the beam 5 and the cross beam 6 of the derrick which is parallel therewith is a horizontal lazy board 8 to the inner side of which is secured a metal bar 9 having a series of brackets or clips I attached thereto adapted to receive and hold the upper end portions of the pipe or tubing sections II stacked in an upright positionwithin the derrick. Each bracket or clip In includes an arcuate upwardly curved spring arm I2 conforming to the contour of the drill pipe or tubing II and pivoted at one end to the bar 9, as at I3, for vertical swing- 1938, Serial No. 198,610

ing movement. Integral with the outer end of and extending at right angles to the arm I2 is a rearwardly projecting arm I4 having its free end portion outwardly offset as at I to provide a transverse shoulder I6 arranged to abut the outer end of the curved arm I2 of the next bracket or clip I0 so that the brackets are effectively interlocked and securely held in horizontal operative position with adjacent brackets or clips defining a closed space in which a pipe or tubing 10 section is positively held until manually released. The free end portion of the arm I4 has a beveled outwardly offset terminal I! spaced from the adjacent end of the arm I4 of the next bracket and provided in its inner side with a recess I8 adaptextreme left of Figure 2, and the pipe sections are engaged with said brackets or clips successively from right to left. When a pipe section is leaned against the arm I2 of a bracket, the latter is caused to swing upwardly to horizontal position, the shoulder I6 of the arm I4 of said bracket being snapped into engagement with the next bracket to the right thereof.

Additional lazy boards 8a similarly provided with brackets or clips may be provided parallel with the lazy board 8, but these must be hinged at one end as at I9 for vertical swinging movement so that they maybe swung upwardly to a vertical position out of the way when not in use. For instance, when the tubing has been removed from the brackets of the lazy board 8a shown, the latter is swung to a vertical position at one side of the derrick as shown in Figures 1 and 2, so as to not interfere with engagement of tubing sections with or disengagement thereof from the brackets of lazy board 8. At the same time, the

lazy board 8a may be swung downwardly to an operative horizontal position as shown by dotted lines in Figure 1 when required for use, the free end thereof resting on beam 5.

In practice, as many lazy boards with brackets may be provided as may be necessary to support the required number of pipe sections. The pipe sections are stacked in an inclined position to assist in holding the brackets or clips closed, and

to rest in the curved arms l2 out of engagement with the locking arms M.

It will be apparent that the device is simple, durable and very efilcient, as well as convenient to install and use. Minor changes in the details of construction shown and described may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. In combination, "a lazy board adapted for attachment to a derrick, and normally depending brackets, pivoted thereon against each of wh'idh a pipe in inclined position is adapted to be placed, the brackets being pivotally mounted on the lazy board to swing upwardly-about a horizontal axis into interlocking relation in r'esponse to placing of pipes thereagainst.

2. In combination, a derrick, a :lazy board mounted thereon, and a plurality of interlocking brackets pivoted on the lazy board, saidbrackets having arouatearms i or receiving pipesin upright ,position and locking zarms for confining the pipes 'in said arcuate arms, the locking arm of .each -brackethaving anoutwardly offset end affording atransverse shoulder engageable-with the-arcuate arm of an adjacent 'bracket. 7

3. :In combination, a derrick, :a lazy board mounted'thereomanda plurality of interlocking brackets pivoted-on the lazyboard, said brackets having-arcuatearms or receiving ,pipes in upend for swinging about a horizontal axis and a locking arm rigid with the other end of said arcuate arm and engageable with the next adjacent bracket *for confining the pipe in the space bee "tween thearcuate=arms of the adjacent brackets.

5. In combination, a derrick, a lazy board mounted thereon, and a plurality of interlocking brackets pivoted on the lazy board, each of said brackets having an arcuate arm pivoted at one end for swing ng about avhorizontal axis and a "locking arm rigid with the other end of said arcuate arm and engageaLblewith the next ad- .Ijacerit bracket for confining-the pipe in'the space between the arcuate arms oithe adjacent'brackets,'the arcuate arms ofthebrackets being curved outwardly andupwardly to cause (the'brackets'to swing upwardly into interlocking relation in response to placing of pipes thereagainst.
